Tools for managing and sharing files
Move files and text between your own devices, prepare batches for sharing and check that copies match. Device sharing pairs two browsers directly; the other tools read files locally and do not upload them.
Sharing and transferring files
Device-to-device file sharing
Send files directly between two devices, paired by scanning QR codes.
Device to device
Shared clipboard between devices
Move text and links between your phone and computer through a paired, direct connection.
Device to device
Large-file splitter and rejoiner
Split a large file into numbered parts and rejoin them later with hash verification.
Renaming and archiving
Archives, checksums and folder inspection
File checksum verifier
Calculate MD5, SHA-1, SHA-256 or SHA-512 and compare with an expected hash.
Folder comparison
Compare two folders and list missing, changed and matching files.
Duplicate file finder
Find byte-for-byte identical files in selected folders.
Folder size analyzer
See which folders and file types take the most space, as a treemap and table.
